采用简单快速的一步浸渍工艺，在AZ31镁合金和A16061铝合金表面成功制备了超疏水表面。处理后的表面由肉豆蔻酸和氧化铈组成，表现出150度以上的静态水接触角。制备超疏水镁合金和铝合金的最短工艺时间分别为60和15 S。通过动电位极化曲线测定，评价了超疏水AZ31的耐蚀性。极化曲线测试表明，超疏水AZ31提高了AZ31镁合金的耐蚀性能。(C)2017爱思唯尔B.V.保留所有权利。
Superhydrophobic surfaces were successfully fabricated on magnesium alloy AZ31 and aluminum alloy A16061 by an easy and ultrafast single-step immersion process. The treated surfaces were composed of myristic acid and cerium oxide, and showed a static water contact angle of more than 150 degrees. The shortest process time for fabricating superhydrophobic Mg and Al alloys were found to be 60 and 15 s, respectively. The anticorrosion resistance of the superhydrophobic AZ31 was estimated by potentiodynamic polarization curve measurements. The polarization curve measurements revealed that the superhydrophobic AZ31 improved the anticorrosion resistant performance of magnesium alloy AZ31. (C) 2017 Elsevier B.V. All rights reserved.
